Definitions

  • the invention relates to a method for producing fruit and vegetable concentrates according to the preamble of claim 1.
  • Fruit and vegetable juices and their concentrates contain a large number of various ingredients that are predominantly positive for health act. Of particular interest are the polyphenols, which include the anthocyanides and the flavonoids and which u. a. antioxidant effects are attributed. On the other hand, in Fruit and vegetable juices often have very high concentrations of sugar and contain acids that have a negative impact on health can, such as B. in caries, diabetes and. etc. ..
  • DE-A-32 29 345 describes the production of a beetroot juice concentrate with an improved composition of the ingredients, namely a concentration of the colors (betalaine) of beetroot juice while reducing the sugar, nitrate and odor content, to a product with u. a. maintain durability.
  • the juice intended for ultrafiltration is squeezed out or obtained by extracting the blanched and shredded tubers.
  • To reduce the viscosity of the juice is a treatment of the crushed Material provided with pectinases. As enzyme treatment is treatment with the pectinases is provided for one hour at 30 ° C.
  • the juice is then used to denaturate dye-degrading Enzymes pasteurized at 65 ° C for 3 minutes or briefly heated.
  • the beetroot juice is used on commercially available ultrafiltration modules with membranes with nominal separation limits between mol weight 1000 and 6000 and temperatures between 1 ° and 25 ° C at pressures between 1 and 20 bar, preferably between 4 and 10 bar ultrafiltered. This method does not lead to an increase in the concentration of flavonoids and / or anthocyanides while reducing sugars and Acids.
  • WO 91 06 226 A describes a method for producing a Fruit or vegetable juice concentrate, the treated, dearomatized Filter product from centrifugation with an ordinary filter after which the filtrate is concentrated.
  • An ordinary filter method is said to be used which is considerable is cheaper than the ultrafiltration equipment previously used. This Process does not work with ultrafiltration.
  • a method according to the invention is provided, which is an enrichment of high molecular weight ingredients with a MW> 500 or polyphenolic ingredients, including anthocyanin dyes, with simultaneous reduction of the low molecular weight ingredients a MG ⁇ 200 or the total sugar content and the acids Fruit and vegetable juices allowed by ultrafiltration.
  • the method according to the invention consists in that for the production a preliminary product a flavonoid and / or anthocyanid-containing fruit and vegetable juice or an equivalent concentrate that is in proportion to water Diluted 1: 2 to 1: 9, with a mixture of pectinases and cellulases, Hemicellulases and / or proteases enzymatically over a period of time is treated for one hour and at 40 ° to 55 ° C, the emerging turbidities are filtered off after sedimentation, and that the preliminary product obtained to obtain the fruit or vegetable juice concentrate is subjected to at least one ultrafiltration, the Separation limit of the filter is between 2,000 and 20,000 daltons.
  • the corresponding fruit or Vegetable juice or a corresponding concentrate for the production of a Pre-product diluted with water To dilute the viscosity
  • an enzymatic treatment is carried out.
  • liquid, highly concentrated pectolytic preparations are used, preferably pectinases and cellulases, hemicellulases and / or proteases, the pectinases being the main activity represent and the other enzymes useful side activities.
  • pectolytic preparations are commercial for fruit juice processing available.
  • the enzymatic treatment is carried out with heating. At the end of the treatment, the diluted concentrate is put on Cooled to room temperature, and then the turbidity is allowed sediment.
  • the turbidity is removed by means of conventional filtration, z. B. bag, candle or nanofiltration, separated. That filtered Sub-product is then pasteurized. Then with the preliminary product according to the invention carried out an ultrafiltration through which the polyphenols be enriched in the retentate, while the sugars and acids be separated by means of the permeate.
  • Ultrafiltration is a pressure-operated membrane process, where the overflow speed is set as high as possible should be.
  • asymmetrical polymers are used for this Ultrafiltration membranes used.
  • the ultrafiltration takes place at a temperature slightly above room temperature.
  • the desired polyphenol concentration in the retentate is reached the ultrafiltration is terminated, the retentate according to the invention Represents end product.
  • the fruit and Vegetable juice concentrates are characterized by an anthocyanin concentration from 2.5 - 5%, i.e. H. there is an enrichment by a factor of 2-5 in front.
  • the proportion of mono- and disaccharides is ⁇ 5%, which is a reduction by a factor of 5 - 20.
  • the water content is 5-70%, which increases by a factor of 1.3 - 2.3 compared to the raw product has been.
  • the fruit and vegetable juices produced according to the invention are therefore ideally suited due to their improved composition, e.g. B. as high-quality food additives in the field of "health food / functional food "to be used.
  • a fruit juice concentrate e.g. from aronia berries or Black currants
  • 65 Brix e.g. from aronia berries or Black currants
  • K.F. water content
  • dye content anthocyanins
  • one Polyphenol content 50-55g / l used.
  • the fruit juice concentrate is diluted 1: 4 with water and then treated enzymatically with an enzyme product (main activity: pectinases / secondary activity: cellulases, hemicellulases) and another enzyme product (main activity: pectinases, secondary activity: proteases), the composition of the fruit juice concentrate containing enzymes being different represents as follows: 20.00% fruit juice concentrate 79.92% water 0.08% Enzymmixtur.
  • the clear intermediate product is then pasteurized, with the holding time 15 seconds at 97 ° C.
  • the preliminary product obtained according to 1. is subjected to ultrafiltration, which when an anthocyanin concentration of 3-4% is reached. Subsequently the retentate is pasteurized with a holding time of 45 sec at 97 ° C. The pasteurized product is the end product.
